Abstract

The invention relates to a sand jetting part, and discloses a cooling structure of a sand coating machine for an iron mold. The cooling structure of the sand coating machine for the iron mold is arranged on the sand coating machine. The sand coating machine sequentially comprises a sand jetting mechanism, a sand box and a mold from top to bottom; the sand jetting end of the sand jetting mechanism is connected with the sand box; the sand box and the mold are detachably connected; a heating device is connected under the mold; a support cylinder is connected to the lower end of the heating device, and is fixedly connected onto an installation plate of the sand coating machine; a base plate is connected between the heating device and the support cylinder; a channel group for cooling water to pass through is arranged in the base plate; a water inlet and a water outlet communicating with the channel group are formed on the base plate. According to the technical scheme provided by the invention, the base plate for the water to pass through is utilized to prevent heat of the heating device from transmitting to the support cylinder, so that the temperature rise of the support cylinder is prevented, the influence of high temperature on the sealing effect of a sealing ring on the support cylinder is avoided, and the operation stability of the support cylinder is improved.

Description

technical field [0001] The invention relates to a sand shooting machine component. Background technique [0002] Iron mold sand-covered casting is a semi-precision casting method. This method uses a metal model and a cast iron cavity that is close to the shape of the casting as a sand box iron mold. The close-shaped iron mold is covered with a thin layer of coated sand to form Molds are used for pouring to make castings. Iron mold sand-covered casting has the characteristics of sand casting, that is, it has a rigid sand mold shell, which makes the overall strength of the sand mold high and does not deform, the casting is easy to demould, and the positioning is reliable and the precision is high, so it has a wide range of applications. The main technological process of sand-coated iron mold production includes several steps such as sand-covered molding, inspection and closing, locking the box and placing the sprue cup, pouring, unpacking the casting, sand cleaning, and moldi...
